for the hamburger I have 3 parts, the html, the css and just 4 lines of JS code (below).I can replace the html that's no big deal, but where exactly would i need to place the CSS and how/where would i save the JS part?If it's too much please don't mind and disregard, it's no big thing, just thought i'd try to see how it looks.Thank you for helping.

alright, i've tried so many things now and keep failing.i placed the html part in the correct html position replacing the 4 spans mobirise puts with the 3 spans incl. the button start- & end-tagsi placed the JS in the body section and the external css in the head section as you explainedall the additional css (as shown on the website) i tried to place in logic spots in the css section using code editor but nothing really worked as expected.i saw a few changes during my experiment but the animation as shown in the link (again below) did not work, unfortunately.

from the css (shown behind the link below) i removed all the social media stuff at the bottom like "Watch on YouTube" and everything after "Created with 'heart' by Ahmad Emran Follow me : ..."

and here the HTML, CSS and JS i used for my experiment.If anybody could simply create a blank page in mobirise with only a menu and adjust the code as needed with the below and send me or publish here it would so very much be appreciated.

WOW!Where are you?you're amaZing!thinking that mobirise uses these 2 classnames it now makes all the sense why i got to the point where my version was in the middle of the menu bar.of course having it in the usual known spot at top right would be quite nice ;-)i will again give what you made a try tonight.not going to give up, even though i was about to a few times already and said 'screw it', haha, i am sure many here know that feeling...but once you get something to work and look the way you want it to what a nice feeling that is.and with everything new you also learned more, which is always a good thing.teamviewer sure would be great, absolutely an option... i'll have to see when is possible since it's my b-day weekend... thanks for all your help, @itsadrian !
